3. RESEARCH METHODOLOGY
This chapter covers the details of the research design, encompassing the methodology and
procedures employed to conduct this research. Over the last few decades, qualitative research is
getting very popular in the fields of Computer Information Systems. Implementation of computer
application systems can significantly change the situation dramatically, for the good or
sometimes, even worse. Many systems do not achieve the goals they had been built for. This is
because the needs of the stake holders had not been completely accounted for. The Information
Systems discipline today is considered, a socio-technical discipline, founded on the need to
reconcile technological solutions with the social and human dimensions of business and the
organizational reality Bonnie K & Joseph A M (2005). As the IT industry has grown into a
service oriented industry, the focus has shifted to building software applications based on the
usability of the software by human interaction and behavior. There is now a branch of study
called the Information technology in a global society (ITGS) where the focus of the study is the
study of the impact of information technology on the people and society for the better or worse.
This approach ensures that users do not just use a technology, but the users are provided with an
enhanced experience of living with it. This has given rise to the evolution of software
development approaches like Agile Programming, RAD and Extreme Programming, over the
years, where the development process centrally involves incorporating user requirements at
every stage. As a result, the final product is usable by the end user. The main focus of this
research is to understand the needs of the senior citizens and then design a software application
to cater to their requirements. The work flow for collecting and consolidating the user
requirements has been designed on the lines of Agile software development. This software
development method is based on repetitive and accumulative advancement, where requests and
elucidations progress by teaming and association with the end users. This approach was adapted
here as it would help in adaptive planning, evolutionary design of the interface, and decision of
business model, development and implementation based on an iterative approach. It promotes
rapid and flexible response to change. This model involves the active involvement of the user
throughout the entire lifecycle thus ensures that user expectations are clearly understood.
Prototyping is used to help users for visualization and collect the changes to the system as it is
being built, ensuring that the system being built is what the users really need. This type of
qualitative research method is called design-based technique for exploration here, facts are
collated by consequent estimation during the process of devising, constructing, and testing an
object of importance. The object in focus could be anything like any apparatus, an application
that is developed from IT, the product to solve a cause that is technical and social in nature, a
structure that is theoretically defined, or just a sum up of a theory. In our case the artifact is the
system or model proposed for the social cause of the senior citizens. In summation, it comprises
of a successive iterations of a phase:
Awareness of Problem Suggestion Development Evaluation Conclusion
The consequent progress attained in the artifact or needs of the senior citizens as it is evaluated
depict the possibilities for unifying the facts that evolves from its schematic planning and
development Bonnie K & Joseph A M (2005), Figueiredo & Dias De A (2010).
The steps in Agile Development Model are:
1. Requirements Planning: Defining the concept, the business functions and data, and the
scope of the system.
2. User Interface Design: Proposal of the functional design, specification of system work
flow and processes.
3. Construction: Building a working prototype of main basic features of the system
components, demonstration of prototype with the users and collecting feedback.
Refining the design based on feedback from the users. Development of the final
prototype.
4. Implementation: Deployment stage, this stage again involves demonstration of the
system to the end users who give the final feedback after which the system requirements
are deployed this completes the implementation of the application system.
The research work flow is designed in two main phases- Research Stage I and Research Stage II.
Research stage I focuses in executing the first two steps mentioned above namely, Requirements
planning and user requirements gathering and specification of a functional model. The Research
Stage II would focus in executing the step 3 that would help in finalizing the final user
requirements. Step 4 would cover modelling research that would include technical architecture
design, development and implementation. The deliverable after every state of the research design
is as shown in figure 3.1.
Figure Error! No text of specified style in document..1 Steps of Research Design
3.1 Research Stage I
Research Stage I pertains to requirements planning and functional design. The research
execution plan comprises of a combination of explorative and survey research. The explorative
part involves review of pertinent literature and the survey; this is aimed at requirements
gathering from domain experts, end users and other beneficiaries. This depicted in figure 3.2.
The primary data from survey and the secondary data from the reports both will be analyzed to
understand the requirements in order to design the system.
Literature Review The details of literature review are elaborated in chapter 2. The following are the details of the
reports referenced.
1. Research Reports of NGOs Agencies working for the Social Cause.
a. Study of proprietary research reports published by Agewell. This Delhi based
NGO established in 1999 and has been working for the cause of senior citizens in
order to empower them and provide the necessary care and welfare of older
persons since the time of its inception. Agewell has a network of over 1500 NGOs
over 6500 volunteers and 70000+ sub-volunteers spread across 540 districts of
India. Agewell interacts with over 2500 older persons and other concerned people
on daily basis through its nationwide network of volunteers.

b. Study of proprietary research reports published by Helpage India. This is another
NGO, that has been actively participating in the Age Demands Action Campaign
of HelpAge International since 2007, they organize different activities for the
underlying theme of assertion of rights and entitlements of older persons in the
country.
2. Research Reports of Government of India for Senior Citizens to understand the
initiatives taken by them.
3. Research Reports of Health issues of Senior citizens published by International
agencies like WHO. This will help to understand the common health problems faced
by the senior citizens.
3.1.1. Analysis Report of Secondary Data from Literature
Analysis of secondary data from the proprietary reports of Agewell and Helpage India revealed
the results shown in fig 3.3
Figure Error! No text of specified style in document..3 Secondary Data Analysis
3.1.1.1 User Requirements Gathering The requirements of the senior citizens have been consolidated based on secondary data from the
proprietary research reports. To validate these requirements a survey was conducted with Senior
citizens in the Navi Mumbai area. This would help in deducing if these requirements from the
secondary sources are sufficient or are there any additional requirements?
3.1.1.2 Sampling Jyeshta Nagrik Association consists of members who are senior citizens of India. The Navi
Mumbai wing has a membership base of nearly 1000 in the Nerul suburb alone. Most of them are
active and well informed and are working for the cause of serving towards the wellbeing of the
senior citizens community. This organization is run by the senior citizens themselves and they
have the involvement with many more of them, this organization was chosen as the best place to
conduct the survey in order to assess the needs of the senior citizens. A convenience sample was
used in this study. The inclusion criteria were: voluntary participant in this study, being 55 years
or older. Apart from this a survey was also conducted among 100 random samples like senior
citizens living in the vicinity, building etc. A questionnaire was designed and distributed among
the senior citizens to be completed by them. This was distributed to all the members of the senior
citizens association in 3 different suburbs in the Navi Mumbai Area, Nerul, Kharghar and Vashi.
Each of these centers has about 1000 members each.

3.1.1.3 Design of Data Collection Instrument A survey form was designed and distributed among the senior citizens to be completed by them.
This was distributed to all the members of the senior citizens association in three different
suburbs in the Navi Mumbai Area, Nerul, Kharghar and Vashi. Each of these centers have about
1000 members each. The survey form was distributed to other senior citizens living in the
vicinity also and they were asked to fill it up at leisure. The final number of forms collected back
with survey completed was 456. The research instrument is given in the Appendix A [Form - A].

3.1.1.4 Primary Data Analysis The primary data collected from the survey was analyzed to understand the following points:
Validation of the requirements that have been identified from the secondary data.
Identifying new requirements
Identifying requirements that can be dropped.
Willingness to adapt and use an Internet based technology, for their health care, essential care
and social interaction with their peers.
The primary data analysis is depicted in figure 3.4.

3.1.1.5 Discussions with Domain Experts – Health Practitioners and NGOs
Discussions with Health Practitioners
Discussions were held with health practitioners to understand, their requirements to help them
serve the senior citizens better. The steps to store medical records and also to understand
regulations to be followed for the same were discussed. The following health practitioners were
interviewed:
Dr.(Mrs.) P. R Chakra- MBBS General Physician
Dr. (Mrs.) Gaiki MD (E & T Specialist)
Dr. (Mrs.) Aruna Mayank MBBS General Physician
Dr. Sundaram MD Surgeon
Dr. Ramani MD
Dr. (Mrs.) Kinjewadekar MD Gynecologist
Dr. G. Padmanabhan M B B S General Physician
Dr. (Mrs.) Hema Anand MD
Dr. P Padmanabhan MD
Dr. (Mrs.) Ratna Pedhamkar MD
Dr. Pedhamkar MD
Dr. (Mrs.) Jyothi Prabhakar MD
Consolidation of Points Discussed
Common health issues with senior citizens: Mainly NCDs like diabetes, hypertension
(BP), dementia, knee problems, heart diseases, frequent fractures, eye problems, and
hearing problems.
One of the doctors stated that out of the diseases mentioned above, the main disease that
India will have to deal in the coming years is diabetes and if technology can be used to
analyse the data so that the cause to fight it can be determined, then it will be a great idea.
The doctor also mentioned that they have been told that India was expected to be the
country with the top most number of cases and that too it will occur with the younger age
group1. Research with data mining tools can be undertaken and the lifestyle of the people
can be analyzed. The system that is being designed should contain the following features:
o Health Monitor
Diabetic blood sugar monitor
Sleep hours monitor
Fitness monitor
Pressure monitor

Diet monitor
o Online Counseling with doctors
o Prediction based on health conditions whether a person is prone to diabetes
o News about drugs
o Tutorial about self-administering insulin
o Reminders to administer insulin
About health records being maintained online, two of doctors opined that this will add
work for the doctors, but may be if the format is standardized, they can be given a
softcopy that can be automatically uploaded into the system. Others felt that this is a good
feature, as most of the patients do not know anything about their records, and it would be
not an issue to enter the details into the system.
Many of the seniors do not realize that they need to visit the doctors, so a little bit of
online counselling would help them to understand and overcome their inhibitions. They
can also be convinced that the best way to address the issue is by going to the doctor.
Most of them need to be made to understand the need for following a good exercise
routine, reduce intake of coffee, sweets and smoking. Their awareness about fitness
should be improved with the help of the system.
The awareness about the NCDs itself can help them to understand why they have to come
for treatment, how could they prevent the incidence of the NCDs.
Regarding the regulations for medical records, the doctors suggested that many
applications based on EMR or EHR are already available, these systems will ensure that
the standards are in place; many of them are free of charge and can be reused so that it
can be used for a large database of users.
Discussions with NGOs Associated with the Social Cause
Discussions were held with social organizations working for the cause of senior citizens, to
understand the needs of the senior citizens from their own experience.

2. Jyeshta Nagarik Association – Mr. Chapke
3. Silver Innings – Mr. Bhavesh
Consolidation of Points Discussed About Requirements for Senior Citizens
The senior citizens should be made to get actively involved in volunteering activities to
help each other.
Most the senior citizens require assistance at home to do regular check-ups, in case of
emergency they need to be able to contact local doctors who are willing to come for
urgent care.
Many health check-up camps are being held but, there should be a way to network
different health service providers to organize more camps.
Many of the seniors do not get the message about these camps and even if they get, they
do not have any awareness so they don’t attend these camps. We should help them to
improve their awareness.
Information about the schemes given by insurance companies and the Government
benefits should reach the senior citizens.
They should be able to network on online forums among others.
Many of them want financial assistance, part time jobs, some of them want to study, and
access to such opportunities could be provided.
Many of the seniors do not understand how to use the health devices like glucometer,
video tutorials in the local language should be uploaded in the site.
Shopping for medical supplies like adult diapers, strips for blood sugar tests etc would be
convenient if it can be delivered to their doorstep.
Many of the senior citizens want assistance at home; they need people who can do day-
to-day jobs, some of them need nurses, or people to attend bedridden patients.
Some of them want to sell property, and need assistance for the same.
Consolidation of Points Discussed About System Requirements
The NGOs welcomed the idea about designing and developing a system to help them to manage
the services for senior citizens. But they had three key concerns:
1. Capital investment: Implementation of any system that would cater to the needs of a
huge community definitely calls for a huge investment of capex for infrastructure. As the
number of users begins to grow, additional infrastructure has to be added.
2. IT operations and training of staff: The management and control of the administrative
functions, and customer support would require investment for training their existing staff;
it would also involve a huge shift in terms of work culture. Additional expenditure would
be to hire IT experts to handle maintenance operations. As a consequence, the focus of
the NGOs gets diverted to handling the IT operations rather than their core task.
3. Application flexibility and sustainability: The system should be user friendly for the
end users to use without much training, the billing and administrative operations should
be easy to handle, the system should be flexible for new add-ons. It should have the
potential to sustain the operations of a huge customer base with a good processing speed,
and efficiently utilize the infrastructure.
3.1.2. Requirements Analysis Summary The study of data from secondary sources, facts from the proprietary reports, and some more
requirements from the survey which is the data from the primary sources showed that the
problems of the elders in the country of India pertain to social set up, legal issues, facilities for
health care, conditions pertaining to psychology, financial needs and relations with other people
in the society. It is also evident that the major areas which they need care is more related to
health. The senior citizens have opined that they are willing to adapt to the changes in social
environment and medical aid Agewell (2010). They are also open to adapt to the use of the
internet technology, for social interaction with their peers. Health is a by-product of emotional
well-being; the objective is to help the senior citizens to have a high wellness quotient by the
following the approach shown in figure 3.5.
The system will help to build their overall wellness by the innovative use of information
technology so that their
Awareness about healthy lifestyle, fitness, disease prevention is improved.
Access to Health care services, home health care services, essential service and
information is established.
Assistance to manage health, wealth and personal portfolio is given.
This will promote their wellness and lead to healthy ageing.

Figure Error! No text of specified style in document..6 Research Stage II
The Research stage II as shown in the figure 3.6 would involve design of the prototype,
demonstration of the prototype to the end users, collecting end user response, analysis of the end
user response, and adding the additional requirements to the prototype. This cycle will continue
till the user requirements are finally refined and the deliverable at the end of the research stage II
is the final prototype. The prototype will be implemented and tested for deployment. This will be
followed by the feedback from the end user, NGOs and health practitioners about the final
prototype.
3.2.5. Design of Prototype Based on the functional model proposed for SCWM, a prototype to demonstrate the basic
features of the system interface was designed for presentation at Senior Citizens Associations.
This was designed based on the primary requirements gathered from the user and analysis of
secondary data from proprietary reports. The prototype was created using Wordpress, a blogging
software. A wire frame for the menu and interface screens was created on the internet. The
openEMR software was integrated in the interface and other health care services were added
with sample data. Health tracker was created using PHP and Mysql.
3.2.6. Demonstration of Prototype at Senior Citizens Associations The demo of the prototype along with a story board, poster and PowerPoint presentation was
done at the following centres. The details of the type and size of sample is mentioned in table

figure 3.12.
Figure Error! No text of specified style in document..12 Steps for Modeling Research
The Modeling Research would be detailed in the Chapter 5.
3.4 Summary of Research Methodology
Research stage I involved the requirements planning and functional design. The approach was a
combination of explorative and survey research. The explorative part involved review of
pertinent literature and requirements gathering from end users by survey, discussions with
domain experts, and other beneficiaries. The primary data from survey and the secondary data
from the reports both were analyzed to establish the needs for enabling the system design
process.
In the research stage II the prototype was designed and demonstration of the prototype to the end
users was conducted, response was collected, analysis of the end user response, was done. This
helped in identifying the additional requirements to the prototype. This cycle continued till all
the user requirements were consolidated. This development would be repetitive and done in
small increments that would eventually enable the inclusion of and refinement of solutions by the
involvement of the end users at all the steps . This approach was adapted here as helped in
adaptive planning, design of the interface, decision of business model, development and
implementation based on an iterative approach. It also enables rapid and flexible response to
change. This model involved the active involvement of the user throughout the entire lifecycle
thus; it ensured that user expectations were clearly understood. Prototyping helped the users
visualize and request changes to the system as it is being built, this ensured that the system being
built is according to the users need.
The details of the technical feasibility study would be detailed in chapter 4 and modeling
research involving the final prototype design would be covered in chapter 5. User Opinion about
the final prototype will also be taken and the details can be found in chapter 6.
